What is a maker?

1. the java. Io. serializable interface does not have any methods and members. Why do we need to implement it? ---------- Maker Interface

The reason is purely to identify that this implementation class can be serialized... to provide a virtual machine with an identifier.

After querying the jdk api documentation, you will know "the serialization interface has no methods or fields and serves only to identify the semantics of being serializable"

2. in Java, there is also a flag that is only used to mark (maker), that is, maker annotation ..... @ Override, @ suppresswarning, etc. These two annotation are only used as a tag to assist the compiler.
